VHF is the more common for tv channels, you are probably thinking UHF
In 1965, the VHF (Very High Frequency) television band in the United States consisted of 13 channels, designated as Channels 2 through 13. These channels were primarily used for analog television broadcasting. The allocation of VHF channels was standardized by the Federal Communications Commission (FCC) to facilitate television transmission and reception across the country.
The VHF channels go from 2 to 13, so there are 12 of them. So, 19 + 12 = 31.
Twelve channels.

Eleven TV channels are in the VHF spectrum. My count is 12 in the USA (2 -13).
There are 12 channels. They are channel 2 through channel 13.
The uniden smh 400d has 36 channels

of course its 12 channels...it's obvious!
There is a possibility of 12 but you will never find all the channels filled even in large markets. Cable is the exception.
